Bug 103764

I know you said no errors, but I'd still like to see your xorg log and dmesg, which should provide additional info about the system if nothing else.

Can you check if MSI is enabled (lspci -nn -vv -d 10de: )? Also see if interrupts are being properly delivered (cat /proc/interrupts)

NV46 had some issues with that, although they should have been fixed in 4.4, which you're running...

The PCI-MSI counter (relative nvkm) is rapidly increasing, if glxgears are running. I tried to count, its about 120 interrupts per second, which seems to be ok, till vsync on 60Hz is enabled.

I seems to be a tuxonice-specific bug. I tried now the standard kernel and all seems to be ok (except the suspend and hibernation, which does not work since 5 years :(

Perhaps they mess around with interrupts? Try disabling MSI anyways... nouveau.config=NvMSI=0
